Oral Surgery/hydroxyapatite


I have a question regarding hydroxyapatite paste.
What is the infection rate compared to material like silicone or medpor?

how difficult is it to remove  Hydroxyapatite?

Ive read that itn can calcify and turn into real bone

Mark - Hydroxyapatite paste is a product that actually becomes part of the bone it is applied to.  Silicone never becomes part of the body and it just sits and never attaches.  This lack of attachemet can produce side effects if it is not stable.  Medpor, like silicone does not become part of the body, but it acts as a framework for tissues to create shape to the area.  It also does not attach and needs to be fixed in place with sutures, wires or other products to create stabilization.

Hydroxyapatite, once it starts to integrate with the bone is quite difficult to remove and may need to be cut out.  That is because it does become a part of the bone as it calcifies.

So the infection rate of hydroxyapatite is not high, as long as the surgeon does not create excess blood accumulation in the area of the hydroxyapatite placement.
